SOME MORE ATTEMPTS AT BLACK AND WHITES

Wednesday, November 09, 2005

I am continuing my efforts in understanding post processing for making digital black and white images. The images I bought back from my Hampi had a few rock shapes which made an ideal subject for black and white conversion. Here is an image I was working on today:



Exif Data:

Canon EOS 350D, 100-400L lens at 100mm, ISO 100, 1/2000sec, f/4.5
No post processing applied.

Here is the black and white image processed with following steps:

1. Channel mixer to convert the image to black and white, RGB values 46, 66, -12
2. Unsharp mask, values 14, 50, 0

After applying unsharp mask, I converted the image to sRGB and used save for web option to save the image for uploading.



For my reference, I had an old image taken during my last trip to Hampi. This was taken using Ilford Pan 100 Black and White film. But you can see that the lighting conditions were different between the two images.
